Journal ArticleDOI
Fluctuating selection: the perpetual renewal of adaptation in variable environments.
TL;DR: The traditional gradualist scheme of weak selection acting on polygenic variation should be supplemented by the view that adaptation is often based on oligogenic variation exposed to commonplace, strong, fluctuating natural selection.

Evolution in the Fast Lane: Rapidly Evolving Sex-Related Genes in Drosophila
Wilfried Haerty,Santosh Jagadeeshan,Rob J. Kulathinal,Alex Wong,Kristipati Ravi Ram,Laura K. Sirot,Lisa Levesque,Carlo G. Artieri,Mariana F. Wolfner,Alberto Civetta,Rama S. Singh +10 more
TL;DR: A relatively high proportion of SRR genes have experienced accelerated divergence throughout the genus Drosophila, and several testis-specific genes, male seminal fluid proteins (SFPs), and spermatogenesis genes show lineage-specific bursts of accelerated evolution and positive selection.
Journal ArticleDOI
Bottlenecks and broomsticks: the molecular evolution of Mycobacterium bovis
Noel H. Smith,Noel H. Smith,Stephen V. Gordon,Ricardo de la Rua-Domenech,Richard S. Clifton-Hadley,R. Glyn Hewinson +5 more
TL;DR: It is described how these forces have shaped not only the phylogeny of this group but also, at a very local level, the population structure of Mycobacterium bovis in the British Isles.
Journal ArticleDOI
Genomic divergence during speciation: causes and consequences.
Patrik Nosil,Jeffrey L. Feder +1 more
TL;DR: This issue draws upon empirical studies in plants and animals, and theoretical work, to review and further document patterns of genomic divergence, and points to how experimental work is now required to move the field from descriptive studies of patterns of divergence towards a predictive framework that tackles the causes and consequences of genome-wide patterns.
Journal ArticleDOI
The Biology of Bird-Song Dialects
TL;DR: An account of the principal issues in bird-song dialects: evolution of vocal learning, experimental findings on song ontogeny, dialect descriptions, female and male reactions to differences in dialect, and population genetics and dispersal are given.
